Sharing computer application activities

ABSTRACT

Information regarding application usage on an actor device may be provided through activity notifications and activity reports. An activity notification describing current application activity on an actor device is sent, via wireless connection, to an observer device which displays the activity notification. Activity notifications provide different granularity levels of information based on a received level selection or based on a distance (proximity) between the actor device and the observer device. An activity report representing the history of application usage on an actor device may be displayed on the actor device. For example, the activity report may be triggered to by displayed when the actor device is placed flat. The activity report provides a graphical representation of the application usage on the actor device for a predetermined time period of prior usage. The graphical representation may comprise a plurality of stripes, each stripe representing a particular application or application type.

CROSS-REFERENCE TO RELATED APPLICATIONS Field of the Invention

This application claims the benefit of U.S. provisional patent application 62/197,486, filed on Jul. 27, 2015. The subject matter of this related application is hereby incorporated herein by reference.

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention generally relates to computer science and, more specifically, to sharing computer application activities.

Description of the Related Art

The rising prevalence of mobile devices is now reflected by the introduction of wearable devices such as smartwatches and smartglasses. However, the social implications and acceptance of using such devices in real-world environments differ when compared to how people respond when traditional computing devices, such as tablets and laptops, on which observers can more easily perceive the user's activities.

As computing devices continue to emerge in smaller and more personal form factors, device usage will continue to encroach on interpersonal interactions. For example, in a work-place environment, such as a meeting in a conference room, it is very difficult to determine what a user is doing on his/her mobile or wearable device during the meeting. Thus, it is difficult to determine whether the user is interacting with work-related applications (e.g., text editor, spreadsheet application, etc.) that are relevant to the meeting or, instead, interacting with entertainment applications (e.g., games, videos, etc.) that are irrelevant to the meeting and serve as distractions. Even in public or social environments, the use of mobile or wearable device can have mixed acceptance, for example, when people around the user of the mobile or wearable device are uncertain whether the mobile or wearable device is currently taking pictures or capturing audio or video of the surrounding group. In sum, because ascertaining what people are doing with their mobile or wearable devices is difficult, especially in settings requiring closer personal interactions, social and workplace acceptance of mobile or wearable devices has been hindered.

As the foregoing illustrates, there is a need in the art for techniques that allow user activities on mobile or wearable computing devices to be more transparent to persons in the vicinity of the user.

SUMMARY OF THE INVENTION

Various embodiments include a computer-implemented method for communicating information related to computing device activity. The computer-implemented method includes detecting a user activity associated with an application executing on an actor device.

DETAILED DESCRIPTION

In the following description, numerous specific details are set forth to provide a more thorough understanding of the present invention. However, it will be apparent to one of skill in the art that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the present invention.

The following description is divided into three sections. Section I describes systems and methods for producing activity notifications for displaying on observer devices. Section II describes systems and methods for producing activity reports for displaying on actor devices. Section III describes various alternative embodiments for sharing computer activities.

Embodiments described herein are directed towards a type of computing called candid interaction, where computing devices provide feedthrough about a user's interactions with application to those around the user. Feedthrough may be in the form of activity notifications or activity reports that provide transparency as to a user's activity on a computing device, especially when that computing device is difficult to observe (such as a mobile or wearable device). For example, a user wearing smartglasses can make an observer aware, via an activity notification sent to the observer's device, that the user is are taking notes, as opposed to checking email during a conversation. As another example, a meeting participant can let others know, via an activity report displayed on their device, that they are not distracted by games or videos on their smartphone, but instead are interacting with work-related applications. In some embodiments, activity reports may display the history of application usage on the actor device. Revealing the nature of our device usage to those in our surroundings may help to make usage of mobile or wearable computing devices more socially acceptable and the sharing of usage information can potentially dissolve discomfort about using devices around others.

Section I Activity Notifications for Displaying on Observer Devices

Information regarding application usage on a device may be provided through activity notifications. An activity notification describing application activity on an actor device may be sent, via a wireless connection, to an observer device which displays the activity notification. In some embodiments, activity notifications are sent to observer devices in real-time to reflect current application usage of the actor device. As used herein, the user of the actor device is referred to as an actor and the user of an observer device is referred to as an observer. Activity notifications may be configured to provide different granularity levels of information detail regarding the application activities on the actor device. For example, activity notifications may be configured to only provide a low level of detail (such as the opening and closing of applications) or a higher level of details (such as specific functions that are being performed on the applications, e.g., sending an email, opening a webpage, etc.).

In some embodiments, the activity notifications provide a level of information detail (referred to herein as level of activity detail) based on a granularity level selection received from the actor using the actor device. In these embodiments, the actor explicitly selects the level of information to be shared with observer devices around the actor. In other embodiments, the activity notifications provide a level of activity detail based on a physical distance (proximity) between the actor/actor device and the observer/observer device. For example, a low level of activity detail may be provided in the activity notifications at a far distance and a higher level of activity detail may be provided in the activity notifications at a closer distance.

Activity Notifications Based on Granularity Level Selection

FIG. 1 illustrates an activity notification environment 100 configured to implement one or more aspects of the present invention. The activity notification environment 100 enables activity notifications based on a granularity level selection received from an actor/user. As shown, the environment 100 includes an actor device 110 and at least one observer device 130 (e.g., 130A-130N) coupled via a network 120. The network 120 may comprise any technically feasible communications or information network, wired or wireless, that allows data exchange, such as a wireless (Wi-Fi) network, personal area network (such as Bluetooth, Wireless USB, IrDA, etc.), wide area network (WAN), a local area network (LAN), and/or the Internet, among others.

The actor device 110 and the observer device 130 may each comprise a mobile or wearable computing device, such as a smartphone, smartwatch, smartglasses, laptop, tablet, and the like. In general, however, the actor device 110 and the observer device 130 may each comprise any computing device configured to perform the embodiments described herein. Each actor device 110 and observer device 130 comprise computer hardware components such as memory for storing software application(s) and data and processors that execute the software application(s) to provide processing engines that enable the operations and functions described herein. The computer hardware components of the actor device 110 and observer device 130 are discussed below in relation to FIGS. 13-14. In this regard, the actor device 110 hosts and executes an actor engine 112 and each observer device 130 hosts and executes an observer engine 132.

The actor device 110 executes an actor engine 112 and one or more software applications 114 and stores a table of level selections (selection levels table 115). For example, the actor engine 112 may be implemented as a suite of plugins to a set of existing software applications, each plugin communicating with a “master” actor engine that receives the data from each plugin and performs the embodiments described herein. As another example, the actor engine 112 may be implemented as a single master engine with an exposed, public application programming interface (API) that other existing software applications share data with by pushing data to the actor engine 112, whereby each software application is responsible for sharing/pushing their data to the actor engine 112. The one or more software applications 114 may comprise common mobile applications, such as a camera or video capture application, web browser application, a social network application, a text editor, an email application, a game application, a multimedia application. Each software application 114 may be associated with a unique graphic icon and/or color that represents the software application 114. In general, the actor engine 112 monitors and detects user activities of the software applications 114, produces activity notifications 117 representing the detected application activities (e.g., through text and/or images), and transmits the activity notifications 117 to one or more observer devices 130 via the network 120.

Each observer device 130 executes an observer engine 132 that receives the activity notifications 117 from the actor engine 112 via the network 120. The observer engine 132 then displays the received activity notifications 117 on a display of the observer device 130. For example, the observer engine 132 may be implemented as a background service configured to receive inbound connections that provide data from an actor device 110/actor engine 112. On receiving this data, the background service may be configured to generate and display activity notifications 117. As another example, the observer engine 132 may be implemented as a foreground process configured to actively poll or request data from an actor device 110/actor engine 112 to ascertain whether or not any new data or information is provided by the actor device 110/actor engine 112.

FIGS. 2A and 2B illustrate examples of different activity notifications that can be implemented in the activity notification environment of FIG. 1, according to various embodiments of the present invention. FIG. 2A shows an activity notification 117 that is received and displayed on a display 210 of an observer device 130 comprising a smartphone. FIG. 2B shows an activity notification 117 that is received and displayed on a display 220 of an observer device 130 comprising a smartwatch. In some embodiments, an activity notification 117 is displayed as an overlay that is displayed over (on top of) any currently displayed applications on the observer device 130.

As shown in FIGS. 2A-B, an activity notification 117 may comprise text data 230 and image data 240. The text data 230 may describe the application activity on the actor device 110. For example, the text data 230 may specify the name of the actor using the actor device 110 (e.g., Haijun, Emily, etc.), an application activity performed by the actor (e.g., taking a photo, opening an application, etc.), and/or the name of the application (or application type) with which the actor is interacting (e.g., photo application, text editor application, etc.). The image data 240 may include a unique icon and/or color associated with/representing the application with which the actor is interacting. In other embodiments, an activity notification 117 may further comprise at least one interactive item (such as a hyperlink or interactive webpage) that is selectable by the observer at the observer device 130. In further embodiments, an activity notification 117 may other forms of data, such as animation, audio, and/or video data that is played back at the observer device 130.

In some embodiments, the activity notifications 117 provide a level of activity detail based on a granularity level selection received from the user/actor using the actor device 110. In these embodiments, the received level selection indicates a granularity level of activities (a predefined set of application activities) that is to be shared with nearby observer devices 130. Mappings between a plurality of different level selections and sets of corresponding application activities are stored in the selection levels table 115.

FIG. 3 is a conceptual diagram of a selection levels table 115 implemented in the activity notification environment 100 of FIG. 1, according to various embodiments. The selection levels table 115 comprises a plurality of entries 301 (such as 301 a, 301 b, etc.), each entry 301 representing a granularity level selection 310 that corresponds to a set of application activities 320.

The granularity level selections 310 may vary from a low level of activity detail (e.g., None 301 a) to a high level of activity detail (e.g., Full 301 e), where the number of application activities that may be included in an activity notification 117 accumulatively increase from the low level to the high level of activity detail. In some embodiments, a particular granularity level selection 310 maps to the set of application activities 320 corresponding to the granularity level selection 310 as well as each set of application activities 320 corresponding to all granularity level selections 310 at a lower level than the particular granularity level selection 310. For example, the Moderate level selection 301 d maps to the set of application activities 320 (e.g., webpage_opened; search_query_performed; weblink_opened) corresponding to the Moderate level selection 301 d, the set of application activities 320 (e.g., application_opened; application_closed) corresponding to the Low level selection 301 c, and the set of application activities 320 (e.g., photo_taken; video_capture_started; video_captured_stopped) corresponding to the Minimal level selection 301 b. Thus, the higher the granularity level selection 310, the more application activities of the actor device 110 that are shared via the activity notifications 117.

The actor engine 112 may receive a selection of a granularity level from the user/actor of the actor device 110. Therefore, the actor may explicitly control the level of information to be shared with observer devices nearby the actor. For example, the actor engine 112 may display a sharing slider on a display of the actor device 110, the sharing slider comprising an interactive slider for selecting the granularity level. In other embodiments, the actor engine 112 may receive the user selection of the granularity level using another interactive mechanism. As described above, the received granularity level selection maps to a set of application activities that may be included in the activity notifications 117. In these embodiments, the actor engine 112 may detect an application activity and produce and transmit an activity notification 117 representing the application activity only if the detected application activity satisfies the granularity level selection. The detected application activity may be determined to satisfy the granularity level selection when the detected application activity is included in the mapped set of application activities.

FIG. 4 illustrates a flow diagram of method steps for producing and displaying activity notifications in an activity notification environment, according to various embodiments of the present invention. Although the method steps are described in conjunction with the systems of FIGS. 1-3, persons skilled in the art will understand that any system configured to perform the method steps, in any order, is within the scope of the invention. In some embodiments, the method 400 may be performed by the actor engine 112 executing on the actor device 110 and at least one observer engine 132 executing on at least one observer device 130.

The method 400 begins when the actor engine 112 receives (at step 405) a user selection of a granularity level for the activity notifications 117. For example, the actor engine 112 may receive the granularity level selection through an interactive sharing slider displayed on the actor device 110. The actor engine 112 also maps (at step 405) the received granularity level selection to a set of application activities that satisfy the received granularity level selection using the selection levels table 115.

The actor engine 112 then detects (at step 410) an activity of an application 114 executing on the actor device 110. The detected application activity may comprise a specific user interaction with the application 114 (e.g., opening or closing the application, sending an email, taking a picture, begin capturing video, etc.). For example, application activities may be detected by the actor engine 112 through a pre-defined API. Applications wishing to share information with observer devices can explicitly inform the actor engine 112 via direct calls to the pre-defined API. As another example, the actor engine 112 may infer application activities by deciphering the running code or messages sent over a network by intercepting network packets and analyzing the network packets for known patterns.

The actor engine 112 then determines (at step 415) whether the detected application activity satisfies the received granularity level selection (for example, by determining whether the detected application activity is included in the mapped set of application activities). If not, the method 400 continues at step 410 where the actor engine 112 detects another activity of an application 114 executing on the actor device 110.

If the actor engine 112 determines (at step 415—Yes) that the detected application activity satisfies the received granularity level selection, the actor engine 112 produces (at step 420) an activity notification 117 representing the detected application activity. For example, the activity notification 117 may comprise text data 230 (e.g., specifying the actor name, the detected application activity, and/or the application name or application type), image data 240 (e.g., comprising a unique icon and/or color associated with the application), animation data, audio data, and/or video data. In some embodiments, the activity notification 117 may further comprise at least one interactive item (e.g., a hyperlink or interactive webpage). In an alternative embodiment, the actor engine 112 may generate notification information needed for the observer engine to generate and display the activity notification 117. The notification information may be collected by a centralized service, for example, run on a local PC or server or an Internet-based cloud architecture, whereby actor engines 112 push notification information to the centralized service and the centralized service identifies observer devices to receive the notification information based on the location, context, and/or granularity settings of the observer devices.

The actor engine 112 then transmits (at step 425) the activity notification 117 to at least one observer engine 132 via the network 120 (e.g., Wifi or Bluetooth). The observer engine 132 then receives and displays (at step 430) the activity notification 117 on a display of the observer device 130. In some embodiments, the observer engine 132 displays the activity notification 117 as an overlay displayed over (on top of) any currently displayed applications on the observer device 130. The observer engine 132 may display the activity notification 117 for a predetermined period of time before removing the activity notification 117 from the display of the observer device 130. In these embodiments, the activity notification 117 may be displayed in the form of a short-lived pop-up message.

The below steps 435-445 comprise optional steps that may be performed if the activity notification 117 comprises at least one interactive item. At step 435, the observer engine 132 receives a user selection of the at least one interactive item and activates/opens at least one interactive item. For example, the observer engine 132 may receive a user selection of an interactive item comprising a weblink to a corresponding webpage that is displayed by opening a web browser application on the observer device 130. The observer engine 132 then transmits (at step 440) a backchannel notification to the actor engine 112 via the network 120. The backchannel notification may indicate that the at least one interactive item was selected at the observer device 130. The actor engine 112 then receives and displays (at step 445) the backchannel notification on a display of the actor device 110. The method 400 continues at step 410 where the actor engine 112 detects another activity of an application 114 executing on the actor device 110.

Activity Notifications Based on Proximity Level

In some embodiments, the activity notifications provide a level of activity detail based on a physical distance (proximity) between the actor/actor device and the observer/observer device. For example, a low level of activity detail (fewer application activities) may be provided in the activity notifications at a far distance and a higher level of activity detail (more application activities) may be provided in the activity notifications at a closer distance.

FIG. 5 illustrates an activity notification environment 500 configured to implement one or more aspects of the present invention. The activity notification environment 500 enables activity notifications based on a proximity level determined from on a distance between the actor/actor device 110 and the observer/observer device 130. The activity notification environment 500 comprises some components that correspond to components of the activity notification environment 100 shown in FIG. 1 and are not discussed in detail here. The components and features of the activity notification environment 500 that are different from the components and features described in relation to the activity notification environment 100 of FIG. 1 are discussed below.

As shown, the environment 500 includes an actor device 110 and at least one observer device 130 (e.g., 130A-130N) coupled via a network 120. In general, the actor device 110 and the observer device 130 may each comprise any computing device configured to perform the embodiments described herein, such as a smartphone, smartwatch, smartglasses, laptop, tablet, and the like.

The actor device 110 executes an actor engine 112 and one or more software applications 114 and stores a table of proximity levels (proximity levels table 515). In general, the actor engine 112 monitors and detects user activities of the software applications 114, produces activity notifications 117 representing the detected application activities, and transmits the activity notifications 117 to one or more observer devices 130 via the network 120. The level of activity detail provided in the activity notifications may be based on a distance between the actor/actor device 110 and the observer/observer device 130 and the proximity levels table 515.

Each observer device 130 executes an observer engine 132 that receives and displays activity notifications 117 on a display of the observer device 130. In some embodiments, each observer device 130 comprises a viewing component 550 that enables simultaneous viewing of the actor/user of the actor device 110 and displaying of the activity notifications 117. The viewing component 550 may comprise a combination of hardware components and software components for providing the simultaneous viewing and displaying functions. For example, the observer device 130 may comprise a smartphone having a viewing component 550 comprising camera or video components (e.g., lens and camera/video software) for viewing the actor and a display for displaying the actor and the activity notifications 117. Thus, the observer may point the lens of the smartphone towards the actor and the smartphone may display a viewing of the actor and also display the activity notifications 117 simultaneously. As another example, the observer device 130 may comprise smartglasses, wherein the glass lenses provide the viewing component 550 for viewing the actor and displaying the activity notifications 117. Thus, the observer may look towards the actor and the smartglasses may provide a viewing of the actor and also display the activity notifications 117 simultaneously on the glass lenses.

FIGS. 6A and 6B illustrate further examples of different activity notifications that can be implemented in the activity notification environment of FIG. 5, according to various other embodiments of the present invention. FIG. 6A shows an activity notification 117 that is displayed on a display 610 of an observer device 130 in far proximity to the actor 650/actor device 110. FIG. 6B shows an activity notification 117 that is displayed on a display 610 of an observer device 130 in close proximity to the actor 650/actor device 110. In the examples of FIGS. 6A-B, the actor device 110 comprises smartglasses and the observer device 130 may comprise a smartphone or smartglasses.

As shown in FIGS. 6A-B, an actor 650 (using an actor device 110) is viewed through the observer device 130 which simultaneously displays an activity notification 117. In some embodiments, the viewing component 550 displays an activity notification 117 as an overlay proximate to the view of the actor 650. For example, the activity notification 117 may be displayed within a message bubble 660 displayed next to the face of the actor 650. The level of activity detail in the activity notification 117 may vary depending on the distance between the actor 650/actor device 110 and the observer/observer device 130. For example, FIG. 6A shows an activity notification 117 with a relatively lower level of activity detail (e.g., an icon representing a game application with which the actor is currently interacting) when the actor 650/actor device 110 is relatively farther away from the observer/observer device 130. In comparison, FIG. 6B shows an activity notification 117 with a relatively higher level of activity detail (e.g., a game score of the game application) when the actor 650/actor device 110 in relatively closer to the observer/observer device 130.

In some embodiments, the activity notifications 117 provide a level of activity detail that is determined by the actor device 110 based on a distance between the actor/actor device 110 and the observer/observer device 130 and the proximity levels table 515. In these embodiments, the level of activity detail indicates a granularity level of activities (a predefined set of application activities) that is to be shared with nearby observer devices 130. Mappings between a plurality of different proximity levels and sets of corresponding application activities are stored in the proximity levels table 515.

FIG. 7 is a conceptual diagram of a proximity levels table 515 implemented in the activity notification environment 500 of FIG. 5, according to various embodiments. The proximity levels table 515 comprises a plurality of entries 701 (such as 701 a, 701 b, etc.), each entry 701 representing a proximity level 710 that corresponds to a set of application activities 720. Each proximity level 710 may correspond to a specific distance range between the actor/actor device 110 and the observer/observer device 130 (e.g., greater than 10 feet, between 7 feet and 10 feet, between 4 feet and 7 feet, etc.).

Each proximity level 710 maps to a level of activity detail and a set of application activities 720 that may be included in the activity notifications 117. Thus, the proximity levels 710 may vary from a low level of activity detail (e.g., far distance 701 a) to a high level of activity detail (e.g., close distance 701 e), where the number of application activities that may be included in an activity notification 117 accumulatively increase from the low level to the high level of activity detail. In general, a lower proximity level 710 corresponding to a farther distance range maps to a lower level of activity detail and a smaller set of application activities 720 than a higher proximity level 710 corresponding to a closer distance range. Thus, the observer is given implicit control over the level of activity detail, and to access the most detail, the observer is required to enter the actor's personal space. In some embodiments, a particular proximity level 710 maps to the set of application activities 720 corresponding to the proximity level 710 as well as each set of application activities 720 corresponding to all proximity levels 710 at a lower level than the particular proximity level 710. For example, a proximity level 701 d (“4 ft>Distance>2 ft”) maps to the set of application activities 720 (e.g., webpage_opened; search_query_performed; weblink_opened) corresponding to the proximity level 701 d, the set of application activities 720 (e.g., application_opened; application_closed) corresponding to the proximity level 701 c (“7 ft>Distance>4 ft”), and the set of application activities 720 (e.g., photo_taken; video_capture_started; video_captured_stopped) corresponding to the proximity level 701 b (“10 ft>Distance>7 ft”). Thus, the higher the proximity level 710, the more application activities of the actor device 110 that are shared via the activity notifications 117.

The actor device 110 may receive, via the network 120, a distance value from the observer device 130 indicating an approximate distance between the actor/actor device 110 and the observer/observer device 130. For example, the observer device 130 may send the distance value to the actor device 110 in a backchannel notification transmitted though the network 120. The actor engine 112 may then determine the appropriate level of activity detail by identifying a proximity level 710 corresponding to the received distance value and mapping the identified proximity level 710 to a set of activities 720 that may be included in the activity notifications 117. In these embodiments, the actor engine 112 may detect an application activity and produce and transmit an activity notification 117 representing the application activity only if the detected application activity satisfies the identified proximity level. The detected application activity may be determined to satisfy the proximity level when the detected application activity is included in the mapped set of application activities.

FIG. 8 illustrates a flow diagram of method steps for producing and displaying activity notifications in an activity notification environment, according to various other embodiments of the present invention. Although the method steps are described in conjunction with the systems of FIGS. 1-3 and 5-7, persons skilled in the art will understand that any system configured to perform the method steps, in any order, is within the scope of the invention. In some embodiments, the method 800 may be performed by the actor engine 112 executing on the actor device 110 and at least one observer engine 132 executing on at least one observer device 130. Some steps of the method 800 are similar to steps of the method 400 of FIG. 4 and are not discussed in detail here.

The method 800 begins when the observer engine 132 determines (at step 802) a distance value indicating an approximate distance between the actor/actor device 110 and the observer/observer device 130. The observer may view the actor through a viewing component 550 of the observer device 130 and the observer engine 132 may determine an approximate distance to the actor/actor device 110 using various techniques. For example, the observer engine 132 may detect the actor's face by implementing a face detection library (e.g., Android's face detection library) and the actor's distance may be estimated based on the width of the actor's face. In other embodiments, other techniques may be used to determine the distance value. The observer engine 132 also transmits (at step 802) the distance value to the actor device 110 via the network 120 (e.g., through a backchannel notification).

The actor engine 112 receives (at step 805) the distance value and identifies a proximity level and a set of application activities that satisfy the identified proximity level. For example, the actor engine 112 may identify a proximity level 710 in the proximity levels table 515 corresponding to the received distance value and map the proximity level 710 to a set of application activities that satisfy the proximity level.

The actor engine 112 then detects (at step 810) an activity of an application 118 executing on the actor device 110. The actor engine 112 then determines (at step 815) whether the detected application activity satisfies the identified proximity level (by determining whether the detected application activity is included in the mapped set of application activities). If not, the method 800 continues at step 802. If the actor engine 112 determines (at step 815—Yes) that the detected application activity satisfies the identified proximity level, the actor engine 112 produces (at step 820) an activity notification 117 representing the detected application activity. The actor engine 112 then transmits (at step 825) the activity notification 117 to the observer engine 132 via the network 120.

The observer engine 132 then receives and displays (at step 830) the activity notification 117 on a display of the observer device 130. In some embodiments, the viewing component 550 of the observer engine 132 displays the activity notification 117 as an overlay proximate to the view of the actor (such as within a message bubble 660 displayed next to the face of the actor). The observer engine 132 may display the activity notification 117 for a predetermined period of time before removing the activity notification 117 from the display of the observer device 130. The method 800 continues at step 802.

Section II Activity Reports for Displaying Application Usage

Information regarding application usage on a device may also be provided through activity reports. An activity report representing the history of application usage/activity on an actor device may be displayed on the actor device. For example, the activity report may be triggered to by displayed on the actor device when the actor device is placed flat on a table, or when it receives a user input to display the activity report. The activity report may provide a graphical representation of the application usage/activity on the actor device for a predetermined time period of prior usage (e.g., the last 10 minutes of application activity). For example, the graphical representation may comprise a plurality of stripes, each stripe representing a particular application or application type. The size of each stripe may represent and correspond to the total amount of time the application or application type was in usage during the predetermined time period. Thus, the user of an actor device may easily convey to others the application usage of the actor device in a transparent and easily understood manner.

FIG. 9 illustrates an actor device 910 configured to implement one or more aspects of the present invention. The actor device 910 may comprise a mobile or wearable computing device, such as a smartphone, smartwatch, smartglasses, laptop, tablet, and the like. In general, however, the actor device 910 may comprise any computing device configured to perform the embodiments described herein. The actor device 910 comprises computer hardware components such as memory for storing software application(s) and data and processors that execute the software application(s) to provide processing engines that enable the operations and functions described herein. The computer hardware components of the actor device 910 are discussed below in relation to FIG. 13.

The actor device 910 executes a report engine 912 and one or more software applications 914 and stores an application table 915. For example, the report engine 912 may be implemented as a background process which continually monitors which software applications are opened and actively being used (executing) via system calls exposed by an operating system of the actor device 110. As another example, the report engine 912 may be implemented as a process that runs and exposes a public API, whereby software applications or processes are able to connect to and push data to the public API to indicate when the software applications or processes are running or which activity/task is currently being completed. As a further example, the report engine 912 may be implemented as a process which continually captures screen images of the actor device and executes computer vision algorithms to recognize which application is currently active. For example, the one or more software applications 914 may comprise common mobile applications, such as a camera or video capture application, web browser application, a social network application, a text editor, an email application, a game application, a multimedia application. Each software application 914 may be associated with a unique graphic icon and/or color that represents the software application 914. The actor device 910 may also include an orientation sensor device 920, such as an accelerometer or tilt sensor. In general, the report engine 912 monitors usage of the software applications 914 on the actor device 910 and, upon detecting an activity report trigger, produces and displays an activity report 917 that graphically represents the history of application usage on the actor device 910.

FIGS. 10A and 10B illustrate further examples of different activity reports that can be displayed by the actor device of FIG. 9, according to various embodiments of the present invention. In some embodiments, an activity report 917 is displayed as an overlay that is displayed over (on top of) any currently displayed applications on the actor device 910. An activity report 917 may provide a graphical representation of the application usage/activity on the actor device for a predetermined time period of prior usage (e.g., the last 5 minutes of application activity prior to the report trigger being detected). As shown in FIGS. 10A-B, the graphical representation may comprise a plurality of stripes 1010 (such as stripes 1010 a-d), each stripe representing and corresponding to a particular application or application type. Each stripe 1010 may comprise image data comprising a unique icon and/or color associated with the corresponding application or application type. The display size of each stripe 1010 may represent the total amount of time the application or application type was in usage during the predetermined time period. Thus, a first stripe 1010 with a larger display size corresponds to an application or application type having a longer time usage compared to a second stripe 1010 with a smaller display size that corresponds to an application or application type having a shorter time usage over the predetermined time period. For example, the pixel width of each stripe 1010 may be constant, but the pixel height of each stripe 1010 may vary depending on the time usage of the corresponding application or application type.

FIG. 10A shows an activity report 917 that shows a history of usage of the actor device 910 per application. In this embodiment, each stripe 1010 corresponds to a specific application 1020 (such as applications 1020 a-d). Each stripe 1010 may comprise image data comprising a unique icon and/or color associated with the specific application. The display size of each stripe 1010 may be based on the total amount of time the application was in usage during the predetermined time period. In further embodiments, the activity report 917 may also contain and display text data that specifies an application name for the application 1020 corresponding to each stripe 1010. For example, the application name may be displayed within or near the corresponding stripe 1010. The activity report 917 may also contain and display text data that specifies the predetermined time period of prior usage (e.g., “History of last 5 minutes”). For example, the predetermined time period may be displayed within or near the plurality of stripes 1010.

FIG. 10B shows an activity report 917 that shows a history of usage of the actor device 910 per application type. In this embodiment, each stripe 1010 corresponds to an application type 1030 (such as application types 1030 a-d). Each application type may be associated with a set of one or more applications (e.g., as specified in an application table 915). The usage time of an application type may be determined by the sum of the usage times of the set of applications associated with the application type. Each stripe 1010 may comprise image data comprising a unique icon and/or color associated with the application type. The display size of each stripe 1010 may be based on the total amount of time that the set of applications associated with the application type were in usage during the predetermined time period. In further embodiments, the activity report 917 may also contain and display text data that specifies the application type 1030 corresponding to each stripe 1010. For example, the application type may be displayed within or near the corresponding stripe 1010. The activity report 917 may also contain and display text data that specifies the predetermined time period of prior usage.

The actor device 910 may store an application table 915 that maps/associates application types to sets of applications. FIG. 11 is a conceptual diagram of an application table 915 implemented in the actor device 910 of FIG. 9, according to various embodiments. The application table 915 comprises a plurality of entries 1101 (such as entries 1101 a-d), each entry 1101 representing an application type 1110 that is associated with and corresponds to a set of applications 1120. For example, for an “Office” application type 1101 a, the application table 915 may specify one or more associated applications (e.g., OfficeApp1, OfficeApp2, etc.), for a “Presentation” application type 1101 b, the application table 915 may specify one or more associated applications (e.g., PresentationApp1, PresentationApp2, etc.), for a “Multimedia” application type 1101 c, the application table 915 may specify one or more associated applications (e.g., MultimediaApp1, MultimediaApp2, etc.), for a “Game” application type 1101 c, the application table 915 may specify one or more associated applications (e.g., GameApp1, GameApp2, etc.), and so forth. In other embodiments, each application type may be associated with a set of applications in a different manner, such as through user-defined application groupings and associations (e.g. if the user places 5 applications into a “productivity” folder representing an application type).

FIG. 12 illustrates a flow diagram of method steps for producing and displaying activity reports on an actor device, according to various embodiments of the present invention. Although the method steps are described in conjunction with the systems of FIGS. 9-11 persons skilled in the art will understand that any system configured to perform the method steps, in any order, is within the scope of the invention. In some embodiments, the method 1200 may be performed by the report engine 912 executing on the actor device 910.

The method 1200 begins when the report engine 912 receives (at step 1205) a user selection of a predetermined time period of prior usage and a user selection for activity reports 917 per application or per application type. The predetermined time period of prior usage comprises a period of time just prior to a report trigger being detected, wherein an activity report 917 represents the time usage of applications over this predetermined time period. In this way, a user of the actor device 910 can control the amount of application usage history that is shared with others. In other embodiments, the predetermined time period of prior usage is set to a default value (e.g., 5 minutes) and the activity reports 917 are set by default as per application.

The report engine 912 monitors and records (at step 1210) the time usage of various applications 914 executing on the actor device 910. The report engine 912 may determine that an application 914 is “in use” when the application 914 is active (e.g., receiving user inputs or interactions, executing software instructions, and/or processing data) and determine that an application 914 is “not in use” when the application is inactive/idle. Often, multiple applications 914 may be open at the same time as a stack of application windows on the actor device 910. In some embodiments, the report engine 912 may determine that an application 914 is “in use” when the application 914 is the currently selected application 914 (as selected by the user) among the multiple applications. The currently selected application 914 may comprise the top/front application in application stack. In these embodiments, the total time that an application 914 is the currently selected application 914 may comprise the total time usage of the application 914. The report engine 912 may continually monitor and record (at step 1210) the time usage of each application 914 executing on the actor device 910.

The report engine 912 then determines (at step 1215) whether a report trigger has been detected. In some embodiments, the report trigger is based on a physical orientation of the actor device 910 (e.g., in relation to one or more axes of a reference plane). In these embodiments, the report trigger may comprise the orientation sensor 920 detecting that the actor device 910 has been placed in an approximately horizontal orientation such that the actor device 910 is placed on a substantially horizontal plane (e.g., when being placed flat on a table or desk). In other embodiments, the report trigger may comprise the orientation sensor 920 detecting that the actor device 910 has been placed in a different orientation. A report trigger may also comprise a different type of trigger, such as receiving a user input to produce and display the activity report 917. If the report engine 912 determines (at step 1215—No) that a report trigger has not been detected, the method 1200 continues at step 1210. If the report engine 912 determines (at step 1215—Yes) that a report trigger has been detected, the method 1200 continues at step 1220.

The report engine 912 produces (at step 1220) an activity report 917 representing the time usage of the applications 914 over the predetermined time period. For example, if the activity report 917 is per application, the activity report 917 may comprise a plurality of stripes 1010, each stripe corresponding to a particular application 914. Each stripe 1010 may comprise image data comprising a unique icon and/or color associated with the corresponding application 914. The display/pixel size of each stripe 1010 may reflect and be based on the total amount of time the application 914 was in usage over the predetermined time period. The activity report 917 may also contain text data that specifies an application name for the application corresponding to each stripe 1010 and/or text data specifying the predetermined time period. For example, if the activity report 917 is per application type, the activity report 917 may comprise a plurality of stripes 1010, each stripe corresponding to a particular application type. Each stripe 1010 may comprise image data comprising a unique icon and/or color associated with the corresponding application type. The usage time of each application type may be determined by the sum of the usage times of each application associated with the application type (e.g., as specified in an application table 915). The display/pixel size of each stripe 1010 may reflect and be based on the usage time of each application type during the predetermined time period. The activity report 917 may also contain text data that specifies an application type corresponding to each stripe 1010 and/or text data specifying the predetermined time period.

The report engine 912 then displays (at step 1225) the activity report 917 on a display of the actor device 910. The activity report 917 may be displayed as an overlay that is displayed over (on top of) any currently displayed applications on the actor device 910. The report engine 912 may display the activity report 917 for a predetermined period of time before removing the activity report 917 from the display of the actor device 910. The method 1200 then continues at step 1210.

Section III Various Alternative Embodiments

This section describes various alternative embodiments for sharing information regarding computer activities with others.

A semantic focus embodiment provides an actor device with a microcontroller knob and mounted projector. The microcontroller knob fixed to the actor device controls the focus and clarity of an image that is projected onto a flat surface by the mounted projector. A current application executing on the actor device is projected onto the flat surface, such as a table. The microcontroller knob may be used to vary the level of information detail that is displayed regarding the current application, whereby more information detail is revealed as a user zooms in to an object of interest and the image gradually transitions from a blurred icon to a clear graphical display on the flat surface. The semantic focus embodiment gives explicit control of information detail to the user of the actor device. Content can be blurred at different levels of granularity. For example, at the coarse level (low level of detail), only the current application icon may be displayed. At a fine level (high level of detail), a graphical display of the full application content may be displayed, allowing the actor's interactions with the application to be observed. Since detail in the miniature view may be difficult to make out, a marquee to show the most relevant information in the current application may be displayed. For example, in a text editor application, the current line of text being edited may be displayed. The coarse and fine levels both transition continuously from blurred to focused as the microcontroller knob is rotated. The actor device may comprise a laptop, but similar implementations could be realized on mobile or wearable devices (where these implementations could also use projectors built-into mobile devices). The microcontroller knob operates by sending rotational information from an attached potentiometer to an Arduino Uno microcontroller.

A status band embodiment provides an actor device (such as a smartwatch) and a status band comprising a light strip. Application activities on the actor device may be sent to the status band which displays a particular light pattern indicating the application activity. Thus, the status band may communicates an actor's application activity through different light patterns. If the observer cannot see the actor device, they can instead see the status band's abstraction of what the actor is doing on the actor device. Different application activities may be mapped to different light patterns. For example, a photo capture activity may be mapped to two quick bright white flashes with all lights, a video recording activity may be mapped to two slow red flashes until recording is stopped, an audio record activity may be mapped to two slow blue flashes until recording is stopped, and so forth. Thus, while the band provides an abstract representation, the information conveyed can be presented with fine granularity. The status band may comprise an RGB LED light strip that is worn on the actor's wrist as a wrist-worn bracelet. It may be made from an off-the-shelf, addressable, RGB LED strip, which is attached to a metal watch clasp and controlled with an Arduino Lilypad.

An iconic jewelry embodiment provides an actor device and jewelry comprising muscle memory wire that is associated with a particular application executing on the actor device. Actor interaction with the particular application executing on the actor device causes a current in the jewelry which causes the shape of the jewelry to change, thus conveying to observers the actor's interaction with the particular application. For example, when the actor interacts with an application, the associated jewelry may moves from a relaxed to a contracted state. The iconic jewelry embodiment communicates application activity though the modality of motion. Each item of jewelry may be color-coded to represent an individual application, with a custom laser-cut acrylic icon attached as a pendant. For example, a necklace jewelry may be associated with an email application, a first earring jewelry associated with a game application, and a second earring jewelry associated with a social network application. Each jewelry piece may be constructed from a strand of Muscle Wire (nitinol), which remembers a specific shape when annealed at a high temperature. The wire takes a relaxed form at room temperature, but reverts to its remembered shape when reheated to roughly 100° C. A 12V electrical circuit may be activated through transistors and an Arduino Uno board. The wires are annealed into helical shapes, causing them to contract when a current is applied. Embroidery thread wrapped tightly around the wire insulates the wire, making it comfortably wearable. A long burst of current may be applied when an application is initially opened, causing the jewelry to contract quickly and noticeably. The jewelry continues to move through more gentle cycles as long as there is ongoing activity in the associated application.

A fog hat embodiment provides an actor device and a fog-generating device that is worn by the actor. Application activity on the actor device may be displayed through a fog above the actor through the fog device mounted on the actor. For example, application icons and application content may be projected onto a screen of mist above the actor's head via the fog device. The content of the display can be further obfuscated by turbulence from a fan. The fog hat embodiment incorporates multiple levels of information detail using a marquee feature for sharing important information. The granularity of information detail is controlled by the actor's selected level. At the coarse level (low level of detail), only the icon of the current application is shown. At the fine level (high level of detail), the display shows more information including a miniature page view and a marquee. This implementation consists of an ultrasonic humidifier, a length of flexible PVC pipe and a custom 3D printed manifold for directing the mist stream. The image is back-projected from a Microvision SHOWWX+ laser projector (5.1×22.9×17.8 cm, 776 g). Affixed to the Fog Manifold is a 5V fan, which can create turbulence to further obfuscate the mist display. An Arduino Leonardo microcontroller operates the fan and a relay switch that turns the mist on or off. The apparatus is connected to the actor device and carried in a small backpack. Advances in miniaturization will eventually allow a similar device to be built into a more amenable form factor. Applications may use different layouts to leverage the fog manifold's inherent turbulence, applications with low privacy needs, such as the web or game apps, place the marquee at the smooth region at the display's bottom, where text and images remain clearly legible. Applications that require greater privacy, such as the email application, place the marquee higher, in the more turbulent region. In this case typing activity is still conveyed to the observer, but the contents are obscured. Decreasing the filter setting to minimal or moderate activates the small fan, which increases privacy further by creating additional turbulence.

In sum, an activity notification environment is provided for enabling sharing of activity notifications regarding application usage on an actor device. An activity notification describing application activity on an actor device may be sent, via a wireless connection, to an observer device which displays the activity notification. Activity notifications may be configured to provide different granularity levels of information detail regarding the application activities on the actor device. For example, activity notifications may be configured to only provide a low level of detail (such as the opening and closing of applications) or a higher level of details (such as specific functions that are being performed on the applications, e.g., sending an email, opening a webpage, etc.). In some embodiments, the activity notifications provide a level of activity detail based on a granularity level selection received from the actor. In these embodiments, the actor explicitly selects the level of information to be shared with observer devices around the actor. In other embodiments, the activity notifications provide a level of activity detail based on a physical distance (proximity) between the actor/actor device and the observer/observer device.

At least one advantage of the disclosed technique is that it provides information regarding application activities of an actor device to surrounding observer devices.

In sum, an actor device is provided for producing and displaying activity reports representing the history of application usage/activity on the actor device. An activity report may provide a graphical representation of the application usage/activity on the actor device for a predetermined time period of prior usage (e.g., the last 10 minutes of application activity). The graphical representation may comprise a plurality of stripes, each stripe representing a particular application or application type. The size of each stripe may represent and correspond to the total amount of time the application or application type was in usage during the predetermined time period. For example, the activity report may be triggered to by displayed on the actor device when the actor device is placed flat on a table, or when it receives a user input to display the activity report.

At least one advantage of the disclosed technique is that it provides information regarding history of application usage on an actor device to those around the actor device.
